Other Parts Discussed in Thread: LM5122
Hello,
If we use a value for slope compensation lower than the calculated value, I think that Vslope will be larger than the voltage actually required.
In this case, what kind of behavior are you concerned about?
The inductance for boost dc/dc of the LM5122 is 2.6uH.
However, there is also a 5.6 uH inductor on the battery input side as a filter in the customer.
The value of Rslope differs depending on calculation at 2.6 uH and 8.2 uH, but they use the value calculated at 2.6 uH.
Therefore, it is smaller than Rslope calculated at 8.2 uH.
Is there any concern that sub harmonic oscillation will occur in this case?
Best Regards,
RYuji
